As the important part of new low-voltage metering cabinet, the performance of watt-hour meter plug influences directly the convenience of operation, the stability of smart meter running and the reliability of metering cabinet. For lacking of the uniform technical specification and an effective, reliably and fast testing method for the performance of plug, this paper proposes a new testing method, it includes the important index of insertion and extraction power and temperature rise. The testing results shows that the method of this paper proposed can detect the mechanical and technical parameters accurately and conveniently, it provides reference for the stability and reliability of metering cabinet.
